WOOD-DECORATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 545,059, dated August 27, 1895.

I Application filed March 28,1893. Serial No. 467,954. (No model.)

To all whom it may concern:

Be it known that I, SPENCER L. DAVIS, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in WVood-Decorating Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention has for its primary object to provide a new and improved construction in devices for the support of the roller-dies of wood-decorating machines at an angle to the bed or bed-roller, and includes in its scope improved means by which the die-roll may be set at various angles, and by which dies of various widths may be accurately and securely held in the die-holder.

To these ends the invention consists in the several matters and combinations hereinafter set forth, and pointed out'in the appended claims.

In the accompanying drawings, which illustrate particular forms of my invention, Figure 1 is an end elevation of a machine containing my improvements. Fig. 2 is a transverse vertical section in the indirect line 2 2 of Fig. 1. Fig. 3 is an end view of the bed and upright portion of the machine, illustrating the roller die-holder in various positions of adjustment. Figs. t, 5, and 6 are detached details of the machine, as shown in Figs. 1, 2, and 3. Fig. 7 is an elevation of a die-holder or 'die'holding bracket of modified form. Fig. 7 is a detached view, in side elevation, of one of the adj usting-screws for the pivot-bars and its block. Fig. 8 is a side elevation of said die-holder of Fig. 7 and of the arm of the maohineframe upon which it is mounted, the latter being shown in section. Fig. 9 is a vertical section in the line 9 9 of Fig. 11, showing the form of lateral guides for the stuff being decorated, adapted to be employed when the table for straight stuff is removed and inthe ornamentation of the outer surface of asweep. Fig. 10 is a horizontal section of the upright and a top view of thebed-roller and rollerguides for sweep work. Fig. ll is a vertical section through the frame in the axis of the bed-roller, showing the bed-roller and rollerguides for sweep work in side elevation.

A represents ahorizontal frame for the support of the shaft of the bed-roller, and Aan upright proceeding from the frame A for the support of the vertically-adjustable overhanging arm A which has a depending outer extremity a.

B is the bed-roller, mounted beneath the arm A in the usual way, upon a shaft which is slowly rotated, either by the gearing shown and usually employed or by other gearing suitable for the purpose. Said bed-roller B has its upper surface elevated above the upper surface of the frame A, and a removable table C is employed for the support and guidance of straight stuff to be operated upon, said table having attached thereto the usual adjustable guide-bars C C, against one or both of which the stuff laterally bears in its movement through the machine.

D represents a decorating-roller or rollerdie by which a desired impression is made in the wood surface as the latter passes through the machine upon the bed'roller and beneath said roller-die. Roller-dies for use in the same machine are of various widths, according to the width of the required decoration, and the support for the roller-die here shown is correspondingly adjustable. As illustrated herein, said support consists primarily of the two arms D D seen in edge view in Figs. 1, 3, and 7, in top view in Fig. 6, and in side view in Figs. 2,5, and 8. These supporting-arms D D are shown in the form of plates which embrace the hub of the rollerdie D between their ends, and sustain the shaft on which said die rotates. In the op eration of sustaining the roller-die with its axis parallel to that of the bed-roller B, these arms D D bear at their upper ends against the under horizontal surface of the arm A An adjustable cross-bolt d, with appropriate clamp-nuts 01 ct arranged to bear respectively on the inner and outer surfaces of the arms D D holds said arms parallel and at a suitable distance apart to properly confine the hub of the roller-die. I11 this it may be aided by a nut 623 on one end of the headed shaft d upon which said roller-die is mounted. These roller-die supportingarms D D are sustained and adjusted laterally to the proper position in the machine by means of ascrew D passing through the lower depending end a of the arm A and provided with set-nuts d on the opposite sides of said arm.

One branch of my invention has especial reference to the adaptation of the roller-die to be set'and sustained in an inclined position and to its further adaptation to a variation of its inclination, in order that an inclined surface of a wood strip may be operated upon without the use of a shoe constructed to bring said surface to a horizontal. For this purpose the roller-die support has adjustable connection or bearing engagement with the inner end of the horizontal adjustingscrew D as, for example, indicated in Figs. 1 and 3-and means are provided, supplemental to the arm A to immediately take the thrust or upward pressure transmitted to the frame from the roller-die. Such supplemental means, as shown in dotted lines in Fig. 1, in full and dotted lines in Fig. 3, an d in the detached Fig. 4, consist in the two bars E E, arranged with their straight lower edges in an inclined position, and in bearing contact with the upper ends or edges of the arms D D To hold the bars E E in agiven inclined position, their more elevated ends are bolted to the arm A bya preferablythrough-bolt e, and their opposite and lower ends may bear against the frame. Said bars E E may be desirably connected together to secure exactly corresponding inclination of both by a cross-barE joining their lower ends, as shown in the detached Fig. 4. The arm D is fastened to the bars E E by means of a bolt e, which passes through said bars and through ears d, formed onthe upper angles of said arm D and extending u'pwardlyoutside said bars E E to receive said bolt. To bring the arms D D and the roller-die to an inclination in which they stand at right angles to the under edges of the bars E E, said arms are rotated on the pivot D by which they are connected With the adjusting-screw D and desirably a set-nut on said pivot is tightened to assist in holding them at this inclination.

By providing the bars E E with slots 6 for the passage of the bolt 6 a variable inclination may be given to said bars to suit a desired inclination of the roller-die. A series of bolt-holes may be employed in the arm A and a series of bolt-holes may he provided in the bars E E, instead of slots 6 A properinclination of the roller-die having been secured to meet the inclined surface of a molding or panel toloe impressed, the bed-guides O O, or the outer one thereof, will be adjusted to laterally hold the stuff in place while being impressed, the under surface of the stuff resting meantime flatly upon the corrugated bed-roller B. The inclination of the roller-die, therefore,'obviz-ites the necessity of placing the molding-strip in ashoe to give the strip a desired inclination to meet the face of the roller-die in its vertical position. Other forms of essentially similar devices for supporting the roller-die in an inclined position are shown in Figs. 7 and 8, wherein a slide F is fitted to the horizontal arm A of the frame, and the die-supporting arms DD are connected at their upper ends with bars F F, which are pivoted on an axis fto said slide F. In this construction the arm A may be either rectangular, T-shaped, or cylindric, as indicated in Fig. 8 by full or dotted lines, and the slide F may be held at a given position thereon by a set-screwf or by any other device adapted for the purpose. For the connection of the arms D D with the pivoted bars F said bars may be provided in their lower edges'with longitudinal T-shaped groovesf and the arms D D with corresponding T-shaped projections d Said arms D D whatever their distance apart, should be so adjusted in the bars F that the pivot fwill be in the plane of the roller-die, in order that the thrust may come directly against said pivot, and thus obviate a tendency to a change of the inclination of the roller-die under the pressure imposed upon it when the machine is at Work. To hold the arms DD in such or a similar adjustment, set-screwsf may be threaded into the T grooves, and detachable pieces of metal f (shown in the detail, Fig. '7 of suitable lengths, may be employed within the T grooves between the setscrews and the T projections on the arms. Other means for. the same purpose may obviously be employed.

It isa characteristic of both forms of devices here shown for the support of the roller-die in an inclined position that they are adapted to be also employed to sustain the die in avertical position. In the construction shown in Figs. 1, 2, and 3, for example, the bars E E may be removed or disused and the same arms D D arranged to bear directly against the under surface of the arm A and in the construction shown in Figs. 7 and 8 the bars F may be swung to the vertical or to any desired'inclined position on the pivotf. The nutf on said boltfmay be made to clamp the bars F firmly to the slide F, so as to retain them at any desired inclination, or other means may be employed for this purpose.

It will be understood that the arm A is vertically adjustable on the upright A in the usual manner and by the usual means of a screw A having a woimnut A operated by a Worm-shaft A provided with a crank a, this adjustment of said arm A being to bring the surface of the roller-die into suitable proximation with the surface of the bed-roller to accommodate a given thickness of molding stuff to be impressed.

Another branch of the invention has refer- IOC ence to the adaptation of the machine to operate upon the outer surfaces of sweeps or curved pieces of wood, and my improvements relating to this feature are mainly shown in Figs. 9, 10 and 11.

The table 0 shown in Figs. 1, 2, and 3 is removable, as stated, and being taken off the machine the bed-roller B projects above the main frame A. A sweep may therefore rest upon the bed-roller with its convex surface upward, as shown by dotted lines in Fig. 9. To guide the sweep properly guide-rollers G are adjustably supported over the roller-bed B by some suitable'means. As such means, they are here shown as being mounted in the forked ends of arms G, which extend lengthwise over the axis of the bed-roller, and are adj ustably fastened to fixed cross-bars H H, which are bolted at their ends to the main frame A, as more plainly illustrated in Figs. 9 and 10. As one form of construction by which the guide-rollers G G may be adjusted toward and from each other, their supporting-bars G are shown as being flat, and providin g each with a slot g, through which passes a clamp-bolt G2 that engages the subjacent bridge 11. Other familiar forms of devices or means for such adjustment of these guiderollers may obviously be employed instead of those shown without departure from the invention, and, generally, various changes and modifications in the construction of the devices shown in the drawings may be made within the scope of the appended claims.

It is to be understood that while my invention is here illustrated in connection with a particular type or form of wood-decorating machines, it may be employed in connection with other forms of such machines, and particularly that any transverse part arranged over the bed-roller and affording direct or indirect attachment for a roller-die support will answer to the arm A of the present description and claims.
